GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 728) = 58968
GCD(648, 728) = ( 648 x 728 ) / 58968
= 648 / 728
= 648
Step2:
LCM(8, 297) = 2376
GCD(8, 297) = ( 8 x 297 ) / 2376
= 8 / 297
= 8
Step3:
LCM(1, 446) = 446
GCD(1, 446) = ( 1 x 446 ) / 446
= 1 / 446
= 1
So, Greatest Common Divisor of 648, 728, 297, 446 is 1
